Bosons and Fermions in Curved Spacetime
Abstract
The Klein-Gordon and Dirac equations are formulated for a classical curved background.The equations are then expressed in Friedmann-Robertson-Walker Universe.Further the equations are solved in R×S3 spacetime. We present general normalizedsolutions to the Klein-Gordon equation together with non-normalized particular solutionsto the Dirac equation in R×S3. The discrete energy quantization and degeneracyare found for both cases.
